Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4202ABRP are determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

• Identical voltage ratings: Breakover voltage (250V, 500V) and off-state voltage (190V, 380V)
• Identical current specifications: Peak pulse current (250A at 8/20µs, 80A at 10/1000µs) and hold current (150 mA)
• Identical on-state voltage: 4 V
• Identical element count: 2 elements
• Identical capacitance range: 50pF, 85pF
• Identical package and mounting: 3-SIP, TO-220 Modified, through-hole mounting

The substitute parts P4202ABL and P4202ABLRP meet all electrical and mechanical requirements for direct substitution. The primary differences are product status (active vs. obsolete) and packaging format (bulk vs. tape & reel).

Parameter Comparison

Engineering Selection Recommendations

Both P4202ABL and P4202ABLRP are valid substitutes for the obsolete P4202ABRP, with identical electrical and mechanical specifications.

P4202ABL is supplied in bulk packaging and is suitable for applications requiring standard component quantities without automated assembly requirements.

P4202ABLRP is supplied in tape & reel format and is optimized for high-volume production environments utilizing automated pick-and-place assembly equipment.

Both substitute parts carry active product status and ROHS3 compliance certification, providing improved regulatory alignment compared to the obsolete P4202ABRP. Selection between P4202ABL and P4202ABLRP should be based on assembly methodology and procurement volume requirements.

Frequently Asked Questions (FAQ)

Q: Can P4202ABL or P4202ABLRP be used as direct replacements for P4202ABRP in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. All voltage ratings, current specifications, element count, capacitance values, and package configurations are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between P4202ABL and P4202ABLRP?

A: The electrical and mechanical specifications are identical. The difference is packaging format. P4202ABL is supplied in bulk packaging for manual or semi-automated assembly. P4202ABLRP is supplied in tape & reel format for automated assembly lines.

Q: Are there compliance differences between the substitute parts and the original P4202ABRP?

A: Yes. The P4202ABRP is RoHS non-compliant. Both P4202ABL and P4202ABLRP are ROHS3 compliant, providing improved regulatory compliance for new designs and ongoing production.

Q: Which substitute part should be selected for automated assembly?

A: P4202ABLRP, supplied in tape & reel format, is designed for automated pick-and-place assembly equipment and is the appropriate choice for high-volume production environments.

Q: Which substitute part should be selected for manual or low-volume assembly?

A: P4202ABL, supplied in bulk packaging, is suitable for manual assembly, prototyping, or low-volume production runs.

Q: Are the mounting and package specifications identical across all three parts?

A: Yes. All three parts use the 3-SIP package in TO-220 Modified configuration with through-hole mounting. PCB layout and assembly procedures remain unchanged.
